RRAS MGM Initialization

  • Article

Applies To: Windows Server 2008 R2

The Multicast Group Manager (MGM) application programming interface (API) enables developers to write multicast routing protocols that interoperate with routers running the Multicast Group Manager. When more than one multicast routing protocol is enabled on a router, the MGM coordinates operations between all routing protocols. The MGM informs each routing protocol when group membership changes occur, and when multicast data from a new source or destined to a new group is received.

After MGM is initialized on the interface, group membership changes can be comunicated.
